Water Worlds of the Milky Way –“Not Life as We Know It” (Today’s Most Popular)

 

Water World

 

“These are utterly different worlds compared to our own Earth,” said Harvard University astronomer Li Zeng about the chances that water worlds are a common feature of the Milky Way, which was heightened by research using computer simulations showing that sub-Neptune-sized planets, that is, planets featuring radii about two to four times that of Earth, are likely to be water worlds, and not gas dwarfs surrounded by thick atmospheres as conventionally believed.

Earth’s current technological civilization is a model for alien-planet evolution, observed SETI Institute astronomer, Seth Shostak “But having now looked for signals for 50 years, we are going through a process of realizing the way our technology is advancing is probably a good indicator of how other civilizations – if they’re out there – would’ve progressed. Certainly what we’re looking at out there is an evolutionary moving target, If AI-powered machines evolved, we would be more likely to spot signals from them than from the “biological” life that invented them,” he added.

“Alien Beacons” — Radio Astronomers Target C-Band Signal from Artificial Interstellar Technology

ESA LaSilla Observatory

 

Astronomers are targeting the radio frequency range between 4 and 8 gigahertz, dubbed the C-band, said Breakthrough Listen principal investigator, astrophysicist Andrew Siemion of the University of California, Berkeley, who announced the release of nearly 2 petabytes of data, the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, the second data dump from the four-year old search for extraterrestrial intelligence (SETI).

“Beyond Kepler” –CHEOPS ‘Alien-Planet’ Space Telescope Delivers First Image

CHEOPS First Light

 

“Now that Cheops has observed its first target, we are one step closer to the start of the mission science,” says physicist Kate Isaak, ESA Cheops project scientist, about the mission to observe bright stars that are already known to host alien worlds that are larger than Earth and smaller than Neptune, by measuring minuscule brightness changes due to the planet’s transit across the star’s disc. “This beautifully blurred image carries the promise of a new, deeper understanding of worlds beyond our Solar System.”
